Effects of hypopressive exercises on pelvic floor and abdominal muscles in adult women: A systematic review of randomized clinical trials

INTRODUCTION

Hypopressive exercises (HE) are postural and breathing exercises that activate deep muscles in the abdomen and pelvic floor. Despite this, there is still no consensus in the literature on its real effectiveness. The objective was to analyze the effects of HE on the abdominal and pelvic floor muscles in women with or without dysfunctions in these regions.

METHODS

This is a systematic review of randomized clinical trials found in the PEDro, PubMed, Cochrane, LILACS, and Embase databases. We include studies that evaluate the effects of HE (with or without other techniques) on the pelvic floor and abdominal region for 8 weeks or more, in women over 18 years old, with or without dysfunction in these regions, with the presence of a control group (active or passive).

RESULTS

HE were effective in improving strength, tone, and reducing symptoms of pelvic floor dysfunctions, in magnitude less than (in two studies) or equal (in one study) to the pelvic floor muscle training (PFMT). When HE were performed with PFMT in the same group, no additional benefits were found. Only one study evaluated abdominal muscles activation, where HE were effective in improving postural control and activation of the transversus abdominis muscle.

CONCLUSIONS

The HE presented positive results to the evaluated parameters. However, the information is still preliminary and scarce. There are methodological divergences regarding the execution, follow-up and standardization of the method, which could affect the results. According to the existing information, HE cannot yet be reliably indicated for the treatment of the pelvic floor, despite pointing out relevant results in some studies. More randomized clinical trials and long-term studies are needed to analyze the effects of HE not only for pelvic floor, but also for other regions, such as abdominal muscles and related dysfunctions.

Can abdominal hypropressive technique improve stress urinary incontinence? an assessor-blinded randomized controlled trial

AIM

To verify which one improves better stress urinary incontinence (SUI) symptoms: abdominal hypopressive technique (AHT) or pelvic floor muscle training (PFMT).

METHODS

Randomized controlled trial. Women with SUI who had not participated of physiotherapy program before were invited. The outcome measures were 7-day bladder diary, International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and pelvic floor muscles (PFM) function measured by Modified Oxford grading System with vaginal palpation and manometry with Peritron. Intervention consisted by 12 weeks of exercises program including PFMT or AHT program, in groups of maximum three women, twice a week, with physiotherapist supervision.

RESULTS

AHT and PFMT groups reduced urinary leakage episodes in 7 days, -0.64 and -1.91, respectively, but PFMT was superior, whit mean difference -1.27 (95% confidence interval [CI]: -1.92 to -0,62) and effect size was 0.94 in favor to PFMT. Regarding to total score of ICIQ-SF, both groups improved, with mean difference between groups -4.7 (95% CI: -6.90 to -2.50) and effect size was 1.04 in favor to PFMT. Manometry also presented improvement after treatment for both groups with mean difference between them of 11 (95% CI: 6.33-15.67) and effect size was 1.15 also in favor to PFMT.

CONCLUSION

Regarding to SUI symptoms, quality of life impact and PFM function both groups presented improvement, however, PFMT was superior to AHT among all of them.
